Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Yeh cause having a range up to 85deg and running at 85deg for prolonged lengths is equivalent. :lol:

Go and run your car for a full tank at 8000rpm and see how that does for it.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

So there must be two completely different kinds of supercapacitor that just happen to fit 3000 F 2.7 V in a 19 x 65 mm can, that have arrived completely unheralded by any reports of this amazing reduction in volume by a factor of 20 or more. Amazing! I know right. How good is that! And here we were...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

What would a hybrid super capacitor graph look like then?

Could there be more than one type of curve that they could produce?

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

But this, and all similar articles, are irrelevant
Why....because they contradict your opinions and interests?

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

As @supercaps said in the 21st post in this thread, there is indeed a lithium based electrode. Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale Post by Supercaps » Sat, 10 Mar 2018, 19:43 Hi. There are no lithium ion cells in the modules. There is a lithium electrode in the graphe...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Found this online which describes non aqueous, hybrid supercapacitor (C-LTO) cells using an AC cathode from 2012. Sounds exactly like what @supercaps has been describing and the paper is 6 years old. I'm sure they would have developed to a lot further by now. We describe in this work the synthesis a...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

I posted in this thread a week ago, a photo and link to a 3 Wh (1.3 Ah) LTO cell that looks exactly like the ones Paul has been testing (blue, with only a negative stripe, and no text to indicate it's an LTO). Here's the link again: https://www.alibaba.com/product-detail/Long-life-Lithium-Titanate-...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Again, thats from $1.30. Get an actual quote.

Shouldn't the curve look similar considering they both have lithium electrodes?
None go down to 0V though.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Actually here is the reply when the manufacture of the LTO electrochemical battery referenced was asked for a quote for a 3Wh cell. "Nice to receive your inquiry. 3W LTO battery cell are 1300mAh capacity. so I can offer you LTO 1865 1300mAh battery cell. the price are USD $2.5." The price you stated...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Can you get 2.7V LTO cells?
If you can what are the cost per cell?
What are the normal costs of 2.4V LTO cells?

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

@supercaps did you get reincarnated after the li-ion cell blew you to supercap heaven?

That was some crazy shit. Definitely do not try this at home.

Great last video too.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Would any of the batteries (assuming not super capacitor inside) be allowed as carry on luggage on an international flight going through the screening?

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

What if....just what if he is actually selling what has been advertised?
Correct me if I'm wrong but the forum rules do state that you must not post any material which is inaccurate.

I just hope that *when* its proven real, that people are as quick to apologise as they were to criticise.
